The organs of the human body they are sets of tissues that perform a specific function in the system. It is an anatomical and functional unit, that is, a series of tissues that perform several functions together. For example: stomach, heart, lung, liver.
The number of organs that the human body possesses is twenty, and each one of them fulfills a fundamental and important function for the proper functioning of the organism.
The organs make up the structural characterization that is made of the body, observing the functional units most important and deducing which are the most important functions of each of them.
The functional organization of the body is the alternative, which rather analyzes the actions carried out by the human body (systems and devices) and based on that thinks the structures that are organized to fulfill those functions.
The organ structure it varies according to the case, being smaller or larger according to the functions that it must have in the body, and the eventual storage that it must do.
Physically, however, organs are classified as solid (having an inner and outer part) and membranous or hollow (having hollow sac morphology).
When a person dies, some of their organs may still be able to function and even medicine has been able to create transfusions.
That is why today people can explicitly declare their will to donate organs to those who need it, so that when they die, their organs can be used in transplants (if the receiving body accepts compatibility).
